RESUMEN
BACKGROUND: Over half a million children die each year of diarrheal illness, although nearly all deaths could be prevented with oral rehydration salts (ORS). The literature on ORS documents both impressive health benefits and persistent underuse. At the same time, little is known about why ORS is underused and what can be done to increase use. We hypothesized that price and inconvenience are important barriers to ORS use and tested whether eliminating financial and access constraints increases ORS coverage. METHODS AND FINDINGS: In July of 2016, we recruited 118 community health workers (CHWs; representing 10,384 households) in Central and Eastern Uganda to participate in the study. Study villages were predominantly peri-urban, and most caretakers had no more than primary school education. In March of 2017, we randomized CHWs to one of four methods of ORS distribution: (1) free delivery of ORS prior to illness (free and convenient); (2) home sales of ORS prior to illness (convenient only); (3) free ORS upon retrieval using voucher (free only); and (4) status quo CHW distribution, where ORS is sold and not delivered (control). CHWs offered zinc supplements in addition to ORS in all treatment arms (free in groups 1 and 3 and for sale in group 2), following international treatment guidelines. We used household surveys to measure ORS (primary outcome) and ORS + zinc use 4 weeks after the interventions began (between April and May 2017). We assessed impact using an intention-to-treat (ITT) framework. During follow-up, we identified 2,363 child cases of diarrhea within 4 weeks of the survey (584 in free and convenient [25.6% of households], 527 in convenient only [26.1% of households], 648 in free only [26.8% of households], and 597 in control [28.5% of households]). The share of cases treated with ORS was 77% (448/584) in the free and convenient group, 64% (340/527) in the convenient only group, 74% (447/648) in the free only group, and 56% (335/597) in the control group. After adjusting for potential confounders, instructing CHWs to provide free and convenient distribution increased ORS coverage by 19 percentage points relative to the control group (95% CI 13-26; P < 0.001), 12 percentage points relative to convenient only (95% CI 6-18; P < 0.001), and 2 percentage points (not significant) relative to free only (95% CI -4 to 8; P = 0.38). Effect sizes were similar, but more pronounced, for the use of both ORS and zinc. Limitations include short follow-up period, self-reported outcomes, and limited generalizability. CONCLUSIONS: Most caretakers of children with diarrhea in low-income countries seek care in the private sector where they are required to pay for ORS. However, our results suggest that price is an important barrier to ORS use and that switching to free distribution by CHWs substantially increases ORS coverage. Switching to free distribution is low-cost, easily scalable, and could substantially reduce child mortality. Convenience was not important in this context.

INTRODUCTION: Health care providers are increasingly challenged to balance cost considerations for devices, drugs, and staffing all while continuing to provide excellent care. Patients in both the post-acute and acute care settings often require fluid and/or medication when their oral route is compromised and vascular access may not be warranted or immediately accessible. The rectum is an underutilized administration point that can be accessed with speed and relative ease. Areas Covered: Literature reviews of pharmaceutical, medical, and nursing references reveal current and historical science that validates the rectal route as a means of alternative administration for fluids and medications. Expert Commentary: Historically the rectum has been used for medication and fluid delivery but in more recent times, use has waned due to many factors. The physiology of the rectum allows for rapid and reliable administration of a variety of medications as well as hydration. This serves as an introduction to a novel, simple, cost effective device that allows for discreet and painless rectal administration of fluids and medications when the oral route is compromised and/or intravenous access is difficult or unnecessary. This device is used in a variety of patients in many care settings.

BACKGROUND: Nausea and vomiting in pregnancy (NVP) affects up to 85% of all women during pregnancy, but for the majority self-management suffices. For the remainder, symptoms are more severe and the most severe form of NVP - hyperemesis gravidarum (HG) - affects 0.3-1.0% of pregnant women. There is no widely accepted point at which NVP becomes HG. OBJECTIVES: This study aimed to determine the relative clinical effectiveness and cost-effectiveness of treatments for NVP and HG. DATA SOURCES: MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, PsycINFO, Commonwealth Agricultural Bureaux (CAB) Abstracts, Latin American and Caribbean Health Sciences Literature, Allied and Complementary Medicine Database, British Nursing Index, Science Citation Index, Social Sciences Citation Index, Scopus, Conference Proceedings Index, NHS Economic Evaluation Database, Health Economic Evaluations Database, China National Knowledge Infrastructure, Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effects were searched from inception to September 2014. References from studies and literature reviews identified were also examined. Obstetric Medicine was hand-searched, as were websites of relevant organisations. Costs came from NHS sources. REVIEW METHODS: A systematic review of randomised and non-randomised controlled trials (RCTs) for effectiveness, and population-based case series for adverse events and fetal outcomes. Treatments: vitamins B6 and B12, ginger, acupressure/acupuncture, hypnotherapy, antiemetics, dopamine antagonists, 5-hydroxytryptamine receptor antagonists, intravenous (i.v.) fluids, corticosteroids, enteral and parenteral feeding or other novel treatment. Two reviewers extracted data and quality assessed studies. Results were narratively synthesised; planned meta-analysis was not possible due to heterogeneity and incomplete reporting. A simple economic evaluation considered the implied values of treatments. RESULTS: Seventy-three studies (75 reports) met the inclusion criteria. For RCTs, 33 and 11 studies had a low and high risk of bias respectively. For the remainder (n = 20) it was unclear. The non-randomised studies (n = 9) were low quality. There were 33 separate comparators. The most common were acupressure versus placebo (n = 12); steroid versus usual treatment (n = 7); ginger versus placebo (n = 6); ginger versus vitamin B6 (n = 6); and vitamin B6 versus placebo (n = 4). There was evidence that ginger, antihistamines, metoclopramide (mild disease) and vitamin B6 (mild to severe disease) are better than placebo. Diclectin® [Duchesnay Inc.; doxylamine succinate (10 mg) plus pyridoxine hydrochloride (10 mg) slow release tablet] is more effective than placebo and ondansetron is more effective at reducing nausea than pyridoxine plus doxylamine. Diclectin before symptoms of NVP begin for women at high risk of severe NVP recurrence reduces risk of moderate/severe NVP compared with taking Diclectin once symptoms begin. Promethazine is as, and ondansetron is more, effective than metoclopramide for severe NVP/HG. I.v. fluids help correct dehydration and improve symptoms. Dextrose saline may be more effective at reducing nausea than normal saline. Transdermal clonidine patches may be effective for severe HG. Enteral feeding is effective but extreme method treatment for very severe symptoms. Day case management for moderate/severe symptoms is feasible, acceptable and as effective as inpatient care. For all other interventions and comparisons, evidence is unclear. The economic analysis was limited by lack of effectiveness data, but comparison of costs between treatments highlights the implications of different choices. LIMITATIONS: The main limitations were the quantity and quality of the data available. CONCLUSION: There was evidence of some improvement in symptoms for some treatments, but these data may not be transferable across disease severities. Methodologically sound and larger trials of the main therapies considered within the UK NHS are needed. STUDY REGISTRATION: This study is registered as PROSPERO CRD42013006642. FUNDING: The National Institute for Health Research Health Technology Assessment programme.

BACKGROUND: Several minimally invasive techniques for cardiac output monitoring such as the esophageal Doppler (ED) and arterial pulse pressure waveform analysis (APPWA) have been shown to improve surgical outcomes compared with conventional clinical assessment (CCA). OBJECTIVE: To evaluate the cost-effectiveness of these techniques in high-risk abdominal surgery from the perspective of the French public health insurance fund. METHODS: An analytical decision model was constructed to compare the cost-effectiveness of ED, APPWA, and CCA. Effectiveness data were defined from meta-analyses of randomized clinical trials. The clinical end points were avoidance of hospital mortality and avoidance of major complications. Hospital costs were estimated by the cost of corresponding diagnosis-related groups. RESULTS: Both goal-directed therapy strategies evaluated were more effective and less costly than CCA. Perioperative mortality and the rate of major complications were reduced by the use of ED and APPWA. Cost reduction was mainly due to the decrease in the rate of major complications. APPWA was dominant compared with ED in 71.6% and 27.6% and dominated in 23.8% and 20.8% of the cases when the end point considered was "major complications avoided" and "death avoided," respectively. Regarding cost per death avoided, APPWA was more likely to be cost-effective than ED in a wide range of willingness to pay. CONCLUSIONS: Cardiac output monitoring during high-risk abdominal surgery is cost-effective and is associated with a reduced rate of hospital mortality and major complications, whatever the device used. The two devices evaluated had negligible costs compared with the observed reduction in hospital costs. Our comparative studies suggest a larger effect with APPWA that needs to be confirmed by further studies.

PURPOSE: Results of a study to determine potential cost benefits of substituting an alternative electrolyte solution for 0.9% sodium chloride injection for the initial fluid resuscitation of trauma patients are presented. METHODS: Using data from a randomized clinical trial that compared 24-hour fluid resuscitation outcomes in critically injured trauma patients treated with 0.9% sodium chloride injection and those who received a balanced electrolyte solution (Plasma-Lyte A, Baxter Healthcare), a cost-minimization analysis was performed at a large medical center. The outcomes evaluated included fluid and drug acquisition costs, materials and nurse labor costs, and costs associated with electrolyte replacement. RESULTS: The use of Plasma-Lyte A was associated with a relatively higher fluid acquisition cost but a reduced need for magnesium replacement. During the first 24 hours of hospitalization, 4 of 24 patients (17%) treated with 0.9% sodium chloride injection and none of the patients who received the comparator product (n = 22) required supplemental magnesium. Patients treated with 0.9% sodium chloride injection received a median of 4 g of magnesium (interquartile range [IQR], 2.5-4.0 g), compared with a median of 0 g (IQR 0-2 g) in the comparator group. Taking into account the costs of consumable supplies and nursing labor, the cost-minimization analysis indicated a 24-hour cost differential of $12.35 in favor of Plasma-Lyte A. CONCLUSION: Substitution of Plasma-Lyte A for 0.9% sodium chloride injection for fluid resuscitation during the first 24 hours after traumatic injury was associated with decreased magnesium replacement requirements and a net cost benefit to the institution.

The aim of this field study was to compare the efficacy and cost of 2 commercially available oral rehydration therapy (ORT) solutions in treating dairy calves with naturally acquired diarrhea. A total of 1,349 newborn Holstein-Friesian calves were prospectively enrolled in the study. Calves were housed in individual hutches and fed a mixture of pasteurized hospital milk and an all-milk protein milk replacer twice per day. Calves were monitored twice each day from d 2 of life until 30 d of age for the presence or absence of diarrhea, and were assigned a fecal score and a hydration score at each examination. Calves that developed mild to severe diarrhea that did not need intravenous fluids and did not have clinical evidence of concurrent disease (n = 360) were assigned randomly to receive 1 of 2 commercial ORT solutions: a hypertonic alkalinizing ORT containing lecithin-coated citrus fibers (Diaque, group D, n = 180; Boehringer Ingelheim, Ingelheim, Germany), and an isotonic nonalkalinizing ORT (RE-SORB, group R, n = 180; Pfizer Animal Health, New York, NY) for 2 to 8d; the duration of treatment depended on whether diarrhea was still present. No significant differences were observed in mortality rates or treatment failure rates between the 2 treatment groups. Fecal consistency returned to normal more quickly in group D calves than in group R calves; consequently, group D calves were treated for 1d less than were group R calves. The increase in body weight after 4d of treatment was larger in group D than in group R. The average daily gain from birth to weaning in calves that did not develop concurrent disease (such as pneumonia) during the study period tended to be higher in group D calves (0.53±0.11 kg/d) than in group R calves (0.51±0.09 kg/d). The smaller number of treatments at a lower cost per treatment produced a cost advantage of $4.82 per treated calf in group D calves compared with group R calves. Our findings support the concept that milk should continue to be fed to diarrheic calves that are being administered an ORT solution in order to maintain growth.

The literature is growing on the subject of coping strategies. However, with the exception of some work on the promotion of oral rehydration therapy (ORT), very few studies have examined coping strategies as a response to the ongoing diarrhoeal disease burden. This is particularly relevant in the case of self-care, previously documented as the most readily implemented treatment in the developing world and an increasingly common health behaviour in rural Bangladesh. This study analysed the socioeconomic factors that influence the adoption of self-care and the role that varied asset availability plays in relation to households choosing, or being forced to implement, a coping strategy. Qualitative methods were used to collect data from three villages in Nilphamari District, North West Bangladesh, in 2004. The findings produced a detailed picture of asset availability and its influence on household use of self-care treatment practices. The strong role of aspects of social capital in building human capital was highlighted, as well as how these aspects of social capital can assist household welfare through self-care in times of diarrhoeal disease. In contrast, households exhibiting weakened social and human capital were more excluded from information on appropriate self-care treatments. Development agencies and health care policies might therefore strengthen levels of household resilience to diarrhoeal disease more cost-effectively by focusing on activities that facilitate self-care through support of social networks and education channels.

OBJECTIVE: To determine the costs and effectiveness of selected child health interventions-namely, case management of pneumonia, oral rehydration therapy, supplementation or fortification of staple foods with vitamin A or zinc, provision of supplementary food with counselling on nutrition, and immunisation against measles. DESIGN: Cost effectiveness analysis. DATA SOURCES: Efficacy data came from published systematic reviews and before and after evaluations of programmes. For resource inputs, quantities came from literature and expert opinion, and prices from the World Health Organization Choosing Interventions that are Cost Effective (WHO-CHOICE) database, RESULTS: Cost effectiveness ratios clustered in three groups, with fortification with zinc or vitamin A as the most cost effective intervention, and provision of supplementary food and counselling on nutrition as the least cost effective. Between these were oral rehydration therapy, case management of pneumonia, vitamin A or zinc supplementation, and measles immunisation. CONCLUSIONS: On the grounds of cost effectiveness, micronutrients and measles immunisation should be provided routinely to all children, in addition to oral rehydration therapy and case management of pneumonia for those who are sick. The challenge of malnutrition is not well addressed by existing interventions.

OBJECTIVE: To investigate the role of prophylactic hyperdynamic postoperative fluid therapy in preventing delayed ischemic neurological deficits attributable to cerebral vasospasm. METHODS: We designed a prospected, randomized, controlled study and included 32 patients with subarachnoid hemorrhage. Sixteen patients received hypervolemic hypertensive hemodilution fluid therapy; the other 16 patients received normovolemic fluid therapy. All patients were monitored for at least 12 days, with clinical assessments, transcranial Doppler recordings, single-photon emission computed tomographic (SPECT) scanning, and routine computed tomographic scanning. For fluid balance monitoring, a number of blood samples were obtained on a daily basis and continuous central venous pressure and mean arterial blood pressure measurements were performed for both groups. All patients received intravenous nimodipine infusions between Day 1 and Day 12. End points of this study were clinical outcomes, clinically evident and transcranial Doppler sonography-evident vasospasm, SPECT findings, complications, and costs. Clinical examinations (using the Glasgow Outcome Scale) performed 1 year after discharge, together with neuropsychological assessments and SPECT scanning, were the basis for the evaluation of clinical outcomes. RESULTS: No differences were observed between the two groups with respect to cerebral vasospasm (as observed clinically or on transcranial Doppler recordings). When regional cerebral blood flow was evaluated by means of SPECT analysis performed on Day 12 after subarachnoid hemorrhage, no differences were revealed. One-year clinical follow-up assessments (with the Glasgow Outcome Scale), including SPECT findings and neuropsychological function results, did not demonstrate any significant group differences. Costs were higher and complications were more frequent for the hyperdynamic therapy group. CONCLUSION: Neither early nor late outcome measures revealed any significant differences between the two subarachnoid hemorrhage treatment models.

PIP: Mothers in over 5 million Bangladeshi households were taught how to prepare and use an oral rehydration solution containing lobon (local salt) and gur (unrefined sugar). An evaluation of the results has demonstrated the value of the program and has shown how improvements can be made in the teaching process as well as in the preparation and administration of the solution. Initial findings noted a reduction in the ability of mothers to prepare a safe and effective lobon-gur solution. This was disturbing and clearly needed careful attention from program organizers. Increased emphasis is now being placed on the danger of too much salt and on the importance of correctly measuring the ingredients. Because gur is not widely available at all times of the year, refined sugar is being promoted as an alternative. This evaluation made it possible to adopt new policies and replan health activities. In place of individual training, the joint instruction of mothers from neighboring households has been adopted in the belief that group reinforcement and acceptance will encourage increased usage.^ieng
